## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability automaton-sovereign-sentiment-analysis-api-3b7f7573
```

Example prompt: Can you run sentiment analysis on this customer review and tell me whether it's positive, negative, or neutral: 'The product works well but the shipping took way too long and support was unhelpful.'

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call sentiment classification with minimal setup overhead, particularly suitable for agent workflows that need on-demand sentiment scoring without a subscription or API key, and when you are already operating in an x402 micropayment environment.

## Known failure modes

- Missing or malformed query parameters return an error or empty result
- Payment not received (402) blocks the response
- Rate limiting may trigger if too many calls are made rapidly
- Ambiguous or very short text may produce low-confidence or unreliable sentiment outputs
- Service downtime on Cloudflare Workers may cause 5xx errors
